| Résumé: | Title screen Using a Bruker IFS 125 HR Fourier spectrometer, the high-resolution spectrum of the 16O35Cl16O molecule is recorded in the region of the ν1+ν3 band, in which more than 2000 transitions with the maximum quantum numbers Nmax = 59 and Kmaxa = 16 are identified. The obtained experimental data are analyzed based on the model from the work [Phys. Chem. Chem. Phys. 23 (8), 4580-4596 (2021)], which takes into account the existence of spin-rotational interactions in the molecule. The root-mean-square deviation of rotational-vibrational energies from the calculated values for the (101) state was drms = 2.5 × 10-4 cm-1, which is 35 times better than the data known from the literature. С использованием фурье-спектрометра Bruker IFS 125 HR зарегистрирован спектр высокого разрешения молекулы 16O35Cl16O в районе полосы ν_1+ν3, в котором проинтерпретировано более 2000 переходов с максимальными значениями квантовых чисел Nmax=59 и Kmax_a=16. Анализ полученной экспериментальной информации выполнен на основе модели из работы (Phys. Chem. Chem. Phys. 2021. V. 23. N 8. P. 4580-4596), учитывающей наличие в молекуле спин-вращательных взаимодействий. Среднеквадратичное отклонение экспериментальных значений вращательно-колебательных энергий от расчетных для состояния (101) составило drms=2.5·10-4cm-1, что в 35 раз лучше по сравнению с известным в литературе результатом.
